FURNACE-RADIATOR-FLUE CLEANER.

Application filed December 19,1921. Seria1No. 523,324.

ed to be inserted in the furnace radiator flue located in many makes of furnaces above the fire pot thereof and through which the heated products of combustion from the fur'nace'pass to the smoke pipe thereof and thence outwardly to the outside. "During such passage, dust, sootand ashesfare deand the flue more or less filled in It is desirable that the interior of the flue or radiator be kept as clean as possible'for'the proper conduction of the heat to the radiator so that thesame may beira di ated therefrom toheatthe air around the radiator which passes through the furnace pipes to theseveral rooms heated by the furnace. Accordingly, it is necessary that the interior of the radiator be cleaned and rid of the accumulation of soot and the like frequently, and it is to the ready accomplishment of this end that the present invention is directed. A primary object and purpose of the invention is to provide a flue cleaner for furnace radiators, simple in conposited struction, and which can be inserted into the clean-out opening.

relating to the practical and.

radiator flue at the clean-out opening there in for any desired distance within the length of the device, and so constructed that it will pass over the deposit of soot, ashes and the like as it is entered into the radiator, but will assume another position when drawn back toward the clean-out opening and scrape the deposit from the inner sides of the radiator and draw it to and out of the Various other objects and purposes, economical production of adevice of this character capable of attaining the ends set forth will appear as understanding ofthe invention is had from the following description, taken in connection with the accompanying drawing, in which, i 7

Fig. 1 is a perspective view ofa simple form of furnace radiatorflue cleaner, made in accordance with my invention."

Fig. 2 is an elevation of a slightly modifled form of construction of the device, and

Fig. 3 is an elevation, with parts broken away and shown in section of' a still further modified form of construction.

' Like reference characters refer to like parts in the diflerent figures of the'dra'wing.

In the construction of the device, as shown in Fig. 1, a circular plate 1 of sheet metal is used, in which two spaced apart sections 2 and 3 of the metal are pressed outwardly I and'formed'into journals for the pivotal connection ofwires or rods therewith as A handle wire 4 of any willlater appear. desired length at one endis formed to pass under the part 2,- and have pivotal connection therewith, as indicatedat 5. Adistance from the connection of the wire 4 to the plate '1, said wire is formed with an eye 6,

andat'its outer-end, saidwire is formed into.

any desired shape of handle, such 'as 7 for ready manual manipulation of. the device. The part 2 is located relatively close to the edge of the circular plate 1, asshownj A second shorter wire or rod 8ha's-piv otal connection are with the plate 1 at the raised section 3sthereof, which is locateda'short distance farther in than the raised section 2 and parallels the same, it being located a distance out from the center ofthe plate. The

opposite end portion of'the wire 8 passes freely through the eye 6 and is. formed into a hook 10 to prevent disconnection from said eye.

The wire 4 is flexible and is designed to bend as required when the plate 1 is inserted into a curved or circular radiator flue. Duringthe insertion, it is evident that the plate 1 may turn toward the wire 4, the

second wire .8 sliding through eye 6 so that the plate passes over the deposit within the radiator flue. As soon as the device is pulled outward, after insertion into the radiator, the plate assumes a position, substan-' tially at right angles to the wire 4, or like that shown in Fig.1, being stopped in such position by the'hook 10, engaging with the eye 6, whereby any deposit 111 front of the plate is drawn outward, and the edges of the plate scrape against the inner sides of the radiator and remove the deposit therefrom.

The device may be moved back and forth as many times as necessary and turned to different positions for the complete scrapingof the inner sides of the radiator flue and removal of the "deposit from said flue out througlrthe clean out opening.

In Fig. 2, the construction is slightly modified in that a light coiled spring 11 is placed around the wire 8 between the eye 6 and the point of connection of the wire to plate 1; This spring is compressed when the plate is moved toward the wire 4, as indicated. in dotted lines in Fig. 2, and aids in throwingv the'plate back to normal full line position. The spring yields when the plate is inserted into the radiator fine but throws the plate back immediately when the device is moved in the opposite dircc tion for withdrawal.

in Fig. 3, the plate l" instead of being flat is dished in term, making a scoop for the remoral and withdrawal of the deposit, being somewhat more ell'ective in operatitm though slightly more ditlicult to manufacture. lVith any of the forms shown, the ready cleaning and scraping of radiator fines in furnaces may be easily accomplished, with the assurance that on outward movement of the device, the plate 1 or 1 assumes its proper position for so 'aping and removing the deposit. The construction is simple, economical to inainifacture and particularly effective for performing the functions for which designed. In practical service it has proved its merit.

I claim:

1. A device of the class described, cont prising a plate of metal, an elongated flexible wire pivotally connected to the plate at one end and adjacent one edge of the plate, said Wire having a laterally extendautomatically ing eye formed in its length between the ends thereot, a second WJJ'G pivotally connected to the plate at one end a short distance from the pivotal connection of the first wire thereto, said second wire passing through said eye, and a stop formed at the free end of said second wire toprevent disconnection Off said second wire from said eye.

2. A device of the class described coin- :nising a plate oi nictal, an elongated flexible wire pirotally connected to the plate at one end and adjacent one edge of the plate, said wire having a laterally extending eye formed in its length. between the ends thereof, a second wire pivotally conneeted to the plate at one end a short distance from the pivotal connection of the first wire thereto, said second wire passing through the eye, a stop formed at the free end of said second wire to prevent disconnection of said second wire from said eye and a coiled spring between the plate wire.

In testimony whereof I altix .IUY signature.
